Study type
Description of intervention(s) / exposure
Participants (13 to 35 yrs in age) will be enrolled. Following screening, a visit prior to first dose will establish baseline measurements of cognitive function, adaptive behaviour scoring and evoked response measurements. Eligible participants will be randomised to one of the following treatments: Treatment A - 50mg BTD-001 taken orally twice daily, as oral solution. Treatment B - 100mg BTD-001 taken orally twice daily, as oral solution. Treatment C - Placebo taken orally twice daily, as oral solution All study treatments will be made up as a flavoured drink solution. Study drug will be given for 12 weeks.

Treatment: Drugs
Comparator / control treatment
Sterile purified water will be used as placebo made up as a flavoured drink and taken as oral solution.
Control group

Primary outcome [1] 287295 0
Safety and tolerability of BTD-001 twice daily oral as assessed by: physical and neurological examinations; laboratory safety tests; ECG; vital signs; adverse event collection. Adverse events are any untoward medical occurrences in study participants administered study treatment.
Based on animal studies and the experience of other people who have received the active ingredient in BTD-001, side effects that may occur include feelings of anxiety and difficulty with sleeping. At very high doses, seizures (fits) and gastrointestinal effects (nausea and vomiting) have been reported to occur. Please note that these side effects have occurred at doses 10-20 times greater than those being tested in this study.
Timepoint [1] 287295 0

Secondary outcome [1] 297850 0
Cognitive, and behavioural/functional effects of BTD-001 in persons with Down syndrome as assessed by psychometric and functional measures. Psychometric measures include standardise tests assessments for functional and adaptative behavior and language. These include: Vineland adaptive behavior scale (VABS-II), Behavior rating inventory of executive function (BRIEF), and Clinical Evaluation of Language Functions (CELF4). Cognitive test assessments will be performed using a computer based testing system [CANTAB(Registered Trademark)].
Timepoint [1] 297850 0

Secondary outcome [2] 297851 0
Effects of BTD-001 on auditory event related potentials (ERP) in persons with Down syndrome. Auditory ERP will be assessed by electroencephalography (EEG).

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients and their carers who consent to take part in the study will be allocated a unique subject number. After screening, eligible patients who meet the inclusion and exclusion criteria will be randomised to 1 of 3 blinded treatments,

An automated system will administer the randomization process and provide the Investigator codes used to assign study drug packaging to subjects.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)

Brief summary
BTD-001, has been used for several decades around the world as a treatment for dementia, a respiratory stimulant and as an ingredient of a cough medication. Studies in a mouse model of Down syndrome (DS) (Ts65Dn transgenic mouse) have demonstrated that chronic administration of the product improved cognition on a number of behavioural assessments. These improvements were sustained months after discontinuation of drug administration, indicating that BTD-001 may cause long-lasting synaptic changes supporting improved cognition. These data indicate that BTD-001, may improve function and cognition in persons with DS and has the potential to improve educational and quality of life outcomes for this population.
